Soldering the Touch Key Sensor Module

Characteristics

1).This module uses ST's STM8S003F3P6 microcontroller I2C / TWI slave control. Touch partially used SJT5101 touch chip, this chip is a single bond touch capacitive touch chip, wide operating voltage range (2.5V ~ 5.5V). Button sensitivity can be adjusted by an external capacitor size, and can automatically adapt to the external temperature and humidity, EMC has strong anti-interference ability, thus making the module more stable and reliable.

2).Using I2C / TWI bus connection between the module and the module, can connect up to 127 This module is a slave device (arduino as I2C / TWI host).

3).Easy to use, can be different shapes according to personal preferences, the type of stitching, can be adapted to different needs.
